VAPO RMSTOVE.

SPECIFICATION forming part of Letters Patent No. 701,475, dated June 3,l1902. Application filed March 11,1901.` Serial No. 50,558. (No model.)

Our invention relates to improvements in vapor-stoves; and its object isto provide a vapor-stove that is safe to use and in which and left torun uninterruptedly withoutturning oil?` until the operator desires tocease using the stove for the time being:

Our invention consists in the peculiarities of construction hereinafterfully described and claimed.

In the accompanying drawings,w hich illustrate our invention, Figure 1isa Vertical sectional View of the4 mechanism, showing the supply-tankin ythe raised position. Fig. 2 is a horizontal sectional View taken onthe dotted line a b of Fig. 1. Fig. 3 is a cross-section View of oneform of our generator. Fig. 4 is a corresponding view of anothermodification of generator, taken on the dotted line c d of Fig. 9. Fig.5 is a side elevation View ot' the generator shown in Figs. lland G.Fig. G is a plan View of the same. Fig. 7is an end elevation View of theform of deilectorshown in Figs. 8 and 9. Fig. 8 isalongitudinal Verticalsectional View of the same. Fig. 9 is a side elevation view of the stovemechanism, with the deiiector shown in vertical section and thesupplemental-burner casing shown in dotted lines, the supply-tank and aportion of its pipe beingremovcd. Fig. 10is alongitudinal verticalsectional view of the supplycontrolling valve, the valve being shownvthe gasolene` maybe turned on and ignited 'casting 5.

y sents another modified form of supplemental end'of which is secured tothe disk 1 and the other end to a valve-casting 5, which is provided'with an oil-passage 6, adapted to be closed by an ordinary valve-stem7, to the outer end of which is secured a thumb disk or headA S.uAn'oidinary stufng-box 9 encircles the valve-stem andhas screw-threadedconnection with the outer end of the valve- The packing for thestuffing-box is indicated in Fig. 2 by 10. The underside of thevalve-casting 5 is provided with a projection 11, having an internalpassage 12 communicating with the passage 6 and having secured in theleft end a downwardly-inclined generator-tube 13, upon the outer end ofwhich is secured a cap 14, having a small Y discharge-hole 15. To morequickly generate vapor from the oil, the tubes 4 and 14 may be lled withfine wires 16.

In lieu of a cylindrical generator-tube, as shown in Figs. 1, 2, and 9,the tube 14 may `have the forms shown in Figs. 3, 4, 5, 6, 13,

and 14. In the forms shown in Figs.. 4, 5, and 6 the tube has aiiattened portion, the sides being pressed toward each other until awide passage is formed with but little depth. As shown in Fig. 3, theilattened portion may also be curved. Filling-wires may or may not beinserted, as desired. In the preferred form of our invention theiattened portion, as shown in Figs. 13 and 14E, has inserted thereinthree at rods, the center one having a diameter slightly less than theinterior of the cylindrical ends. The rods indicated by 1G in this fornimust not, of course, entirely iill the interior of the tube; but a smallpassage or passages must be left between themfor the oil.

Upon the top of the disk 1 is placed the ordinary burner consisting of acap' 17, having lateral openings 1S. Directly below and concentric withthe cap or main burner 17 the IOO disk 1 is provided with a centralopening in which is secured the upper end of the mixing-chamber 19,comprising a vertical liaring tube, the large end being at the top. Themixing-chamber 19, near the lower end, is provided with a lateralopening through which discharges a downwardly-inclined conductor 20, theupper and outer end of which is under the cap 14, so as to receivetherefrom any liquid oil passing from the generator-tube 13. The upperouter'part of the conductor 20 is cut away, so that air may be taken inwith the vapor which is emitted from the pipe 13 when the oil has begunto generate into vapor.

Located directly below the pipe 13, which we term the primary generator,is the supplemental burner 21, comprising a body portion cylindrical inform and having a chamber 22 in the upper part, from which leads anopening 23y in the top of the said supplemental burner. The said chamberis connected with the mixing-chamber 19 by an inclined pipe 24, the saidpipe connecting with the mixing-chamber belowl the lateral openingtherein.

Encircling the burner 21 is a tubular casing 25, preferably ofperforated sheet metal, to admit air, but preventing the iiame from theburner passing laterally outward. This casing rests upon a flange 26 onthe lower end of the burner and extends vertically to a point above thetube or pipe 4, openings being provided in its sides for the extensiontherethrough of the pipe 4 and the primary generator-tube 13, as well asthe inclined pipe 24. An opening 27 is provided near the bottom for theinsertion of a lighted match for igniting the gasolene in the burner 21.

Above the casing 25 is a curved deflect-or 28, which deflects the iiameof lthe oil burning in the casing to the burner17, thus igniting thevapor passing therefrom when vapor begins to pass from the primarygenerator 13. This deflector can be in the form of a curved disk, theconcave side being down, as shown in Fig. 1, or it may be in the formshown in Figs.- 7, 8, and 9-that is, in the form of a trough with theconcave side down and the channel formed thereby being parallel with thetube 4, to which the deflector may be secured by means of two horizontalarms 29, extending from the sides of the pipe 4 and secured at theirends to the sides of the deliector. In the form of deflector shown inFig. 1 the deflector 28 may be secured by a screw 30 to the under sideof the stove-frame, a part of which is shown in section in Fig. 1 andindicated by 3l.

From the lower end of the chamber 22 of the supplemental burner 21through the body of the burner extends a vertical internal oilpassage32. Connecting therewith are inclined passages 33,which lead upwardlytherefrom to a horizontal annular groove 34, which encircles theperipheryof the burner 21. Lateral passages 35 lead from the lower endof the chamber 22 to the exterior of the burner.

In the passage 32 may be placed asbestos wool 36, which restricts thepassage of oil through this passage. Thus when the oil enters thechamber 22 through the inclined pipe 24 the restricted passage 32 willnot convey all the oil that enters the chamber, and most of the oil willpass through the openings 35.to the outside of the burner, where it canbe ignited by inserting a match through the opening 27 in the casing 25.In the event that the valve 7 leaks or is not tightly closed when thestove is not in use the oil entering the chamber 22 after passingthrough the generator 13, in-

clined conductor-pipe 20, mixing-chamber 19,

and pipe 24 will pass through the internal passage 32, which issufficiently large to carry a small amount of oil.

Located below or lower than the burner 21 is a closed vessel orreceptacle for waste oil, (indicated by 37,) which is connectedbyahorizontal pipe 38 bymeans of a T-joint 39 with the lower end of theburner 21, so as to receive the oil passing through the passages 32 and33. A plug 40 closes the end of the T- joint opposite the pipe 38 whenonly one burner is used. It is obvious, however, that the pipe 38may beconnected to other burners constructed like the burner 21 by inserting apipe in place of the plug 40.

Below the waste-receptacle 37 is a valve comprising an outer casing 41,which is provided through its length with a tapering bore in which isrotatably fitted a rotary member 42, provided, as shown in Figs. 1, 10,and 1l, with a longitudinal .axial opening 43, which connects interiorlywith a Vertical pipe 44, which is rigidly secured at its lower end tothe right end, as shown in Fig. 1, of the rotary member 42. To the upperend ofthe pipe 44 is secured a supply-tank 45. The opposite end of themember 42 is screw-threaded and has mounted thereon a nut 46, whichbears upon a concave-convex spring-washer 47, which in turn restsagainst the end of the member42. The spring tension of the washer holdsthe tapered member 42 snugly against its seat in the outer shell orcasing 41, thus preventing leakage in the valve at this point. Theopening 43 does not extend clear through the member 42, but is connectednear its let't end, as viewed in Fig. 1, by means of an opening 48, withan annular peripheral groove 51 in the member 42. Through the casing ICOIIO

41 of the valve and connecting interiorly passage 50, disposed oppositethe groove 51 of the rotary member. The left end of the pipe 49 isconnected to a T-joint 52, which in turn is secured to the lower end ofthe vertical pipe 3.- A plug 53 closes the end of the T-joint oppositethe pipe 49; but this may be displaced by a pipe when the apparatusemploys another Vapor-burner. It will thus be seen that the supply-tank45 may supply oil to several burners and the waste-receptacle may beemployed to receive oil discharged from a plurality of burnersconstructed the same as the one shown in Fig. 1. Inasmuch as the otherburners or burner mechanisms would be simply duplicates of the one shownin Fig. 1, it is deemed unnecessary to show such in the drawings.

Our invention is operated as follows: Oil is :first placed in thesupply-tank 45, from which it 'Hows When the tank is in the positionshown in Fig. 1 through the pipe 44, thence into the opening 43, thencethrough the opening 4S, groove 5l, and opening 50 into the pipe 49. Fromthis pipe it flows through the T-joint 52 and pipe 3 into the passages 2of the generator1 disk 1. From here it passes through the pipe 4 intothe oil-pas sage 6 in the valve-casting, where it is held by the Valve7. If now the valve be opened by turning the stem 7 through theintermediacy of the thumb-piece or head 8, the oil will pass past thevalve-stem 7` into the passage 12 and thence into and through thesupplemental or primary generator 13, from Which it escapes by means ofthe small pinhole 15 of the cap 14. After passing from the generator theoil will be carried downward by means of the conductor 2O through thelateral opening of and into the mixingchamber 19, from which it willpass `by means of the pipe 24 into the chamber 22 of the burner 21. Mostof `the oil will be carried from there through the openings 35 to theexterior of the burner-body 2l, Where it is ignited by inserting alighted match through the opening 27 of the perforated casing 25. lf allthe oil is not consumed as fast as it passes to the exterior of theburner, the surplus or Waste Will pass into the groove 34 and thence bymeans of the passages 33 into the T-joint 39, from which it passes tothe Waste-receptacle 37 by the pipe 3S. The bottom of the receptacle 37is provided with an opening, in which is secured a projection 54 on thecasing 41, provided with avertical hole 55, extending through the casing41 and adapted to register with a hole 56, which extends through therotary portion of the valve from one side and connects With the axialopening 43 therein. The hole 56 registers with the hole 55 When therotary member 42 is turned as shown in Figs. 10 and 11 or at rightangles to the position indicated in the View shown in Fig. 1. VhenI theValve member 42 is turned to the position shown in Figs. 10 and 11, thesupply-tank 45 and pipe 44 will be turned to the horizontal position, inwhich position the gasolene may be poured into the tank 45. After thetank is filled the supply-tank is raised to the Vertical position shownin Fig. 1, thus rotating the valve member 42 and shutting off connectionbetween the holes 55 and 5G. After the lighted match has been applied tothe gasolene passing through the burner 21, as already described, nofurther attention need be directed to regulating or shutting oft thegasolene by turning the Valvestem 7 until the operator has finished withusing the stove. The oil passing from the generator 13 will continuepassing through the pipe 24 into the burner 2l until the generator-pipe13 is heated sufficiently by the oil burning in the casing 25 to causethe oil in the generator 13 to turn into vapor, which, emitted from theopening 15 in the cap 14, will pass into the mixing-chamber 19, carryingwith it a sufficient amount of air for perfeet combustion. The mixedvapor and air Will pass from the top of the mixing-chamber into theburner 17, from which it Will pass through the openings 18. The flame ofthe gasolene burning in the casing 25 will be deiecte'd by the defiector28 against the Vapor emitted from the holes 18 of the burner 17, thusigniting the vapor, which can then be used for heating or cookingpurposes. The heat from the burner 17 Will by conduction heat 4the disk1 in a short time sufficiently to cause the oil passing through thepassages 2 to be generated therein into vapor, and the Vapor generationfrom this time on will be done in the main generator or passages 2. Thevapor generated therein will pass through the same channels as the oilto the generator-pipe 13, Which at this time becomes simply a conductorfor the vapor. The oil of course Will cease passing into the burner 21when the vapor is rst generated in the pipe 13, and the flame in theburner 21 Will soon burn out,there being no oilsupply therein to feedthe ame after the oil ceasestoenterthechamber22. ltwillbenoted that inthe construction of the burner 21 there is provided no means by Which apool of oil can collect. If more oil enters than is immediately burned,the excess passes,as described hereinbefore, through the openings 33 andthence into the Waste-receptacle, Where it remains until the supply-tank45 is disposed in the loWer position, at which time the position of theValve member 42 is suchv that all the oil will pass from theWaste-receptacle 37 into the supply-tank. It will be observed that it isWholly unnecessary for the valve 7 to be turned off during the Wholetime the stove is in use. The excess oil passing through a closedconductor into the waste-receptacle prevents any danger arising from oilpassing in a liquid state into the mixing-chamber. So, also, if theValve 7 should leak or be left open and the burner not ignited nopossible harm could follow, as the oil would pass into theWastereceptacle and not flow out on the floor of the room containing thestove. The Wastereceptacle may be made sufficiently large to hold allthe oil that would pass from the supply-tank 45 and pipe 44. Thus if thevalve should leak badly or be left open unintentionally and the burner21 not ignited no bad result Would happen. The oil would all pass intothe receptacle 37. If, then, the tank 45 Were placed in the lowerposition, then the oil would run from the Waste-receptacle into thetank, which could then be raised, after which the oil would pass againinto the generators, as described. lf when the tank 45 is IOO IIO

lowered to fill with gasolene the valve 7 should not be closed and theburner 17 were left burning, no bad effects could be produced, for thereason that when the tank 45 is in the lower position as well as in theraised position the connection between the passage 43 of the rotarymember 42 and the passages leading to the generators is unbroken andthepressure of the vapor in the generator-passages would force the gasoleneinto they supply-tank 45 and the iiame of the burner 17 would beimmediately extinguished owing to lack of vapor-pressure. Were thesupply-tank 45 cut off from the generator-passages when the tank is inthe lower position the pressure of the Y vapor' in thegenerator-passages would cause the burner 17 to continue to burn forsome time, thus presenting a possible chance for the vapor from theiilling-can to become ignited from the flame of the burner 17, withdisastrous results, may be.

By having the mixing-chamber flaring or increasing in size toward itsmouth or discharge end a much better mixture of vapor and air isproduced than by having a chamber `having a discharge-opening of smallerarea than the admission-opening. The tendency of the compressed vaporissuing from the generator-pipe 13 is to expand, and by increasing thesize of the mixing-chamber toward its outlet end the resistance to thisdisposition of the vapor to expand is reduced, resulting in a greaterintake of air, and thus affording better combustion. By permitting thegasolene to i'iow continuously through the burner 21 instead ofcollecting in pockets or pools the excess of carbon in the iiame fromthe burner 21 is prevented, and the iiame is practically smokeless andvoid of noxious odors and the emission of soot. It will thus be seenthat our invention provides ar construction of vapor-stove that is quitesafe to use and requiring little attention in its manipulation.

Our invention may be variously modified from the construction shownwithout departing from its spirit. i

Having thus described our invention, what we claim, and desire to secureby Letters Patent, is-
